Subject: [PATCH] ARM: mach-shmobile: sh73a0 PINT IRQ base fix
Date: Tue, 17 Jan 2012 11:05:40 +0000 [thread overview]
Message-ID: <20120117110540.5414.77262.sendpatchset@w520> (raw)
From: Magnus Damm <damm@opensource.se>
Bump up the sh73a0 PINT IRQ base from 768 to 800 to avoid
collision with INTCS vectors for IRQ16->IRQ32 at 0x3xxx.
Without this fix the sh73a0 IRQ pin handling code collides
with the PINT code which results in hangs on Kota2 during boot.
